Mamta A. Satoor updated DERBY-2599:
-----------------------------------

    Attachment: DERBY2599_Set_collation_for_aggregates_v1_stat.txt
                DERBY2599_Set_collation_for_Max_Min_v1_diff.txt

Commited attached patch using revision 540237. The commit comments are as follows

Commiting patch DERBY2599_Set_collation_for_aggregates_v1_diff.txt attached to DERBY-2599.
This patch sets correct collation type for MAX and MIN aggregate functions. These 2 aggregate
functions can return string datatype and this return datatype should take it's collation from
it's operand. It appears that these 2 functions can't be used in where clause but even then,
I think they should have correct collation set on them.

> DTD has TypeDescriptorImpl in it which has 2 new fields, namely, collationType and collationDerivation.
These 2 fields are available for all different types of DTDs but only apply to character types.
The other datatypes should ignore these 2 fields.
> This Jira is a placeholder for loading the correct values into collationType and collationDerivation.
